underwent ureteroscopy, 9 underwent retrograde intrarenal surgery (RIRS) and 16 underwent combined RIRS and percutaneous nephrolithotomy. JJ stents were postoperatively placed in 33 patients (66%).• The study cohort self-reported a significant decrease in erectile function ( P = 0.007), intercourse satisfaction ( P < 0.001), orgasmic function ( P = 0.001), sexual desire ( P < 0.001) and overall satisfaction ( P = 0.002) at 1 month following endourological procedures.• This dysfunction was not related to chronic disease, age, smoking, preoperative or postoperative stenting, type of procedure, operative duration or surgeon expertise.• The sexual function of all subjects returned to baseline within 3 months ( P < 0.005). Postoperative erectile function in the stented group revealed a negative tendency that did not reach statistical significance. CONCLUSIONS• Endourological procedures are associated with temporary postoperative sexual dysfunction, which completely recovers within 3 months.• The impact of postoperative stenting on sexual function was not significant.• These findings contribute to enhanced preoperative patient counselling.
